FASTENING-DRIVING MEANS FOR WELTS.

Application led April 27, 1926. Serial No. 104,936.

My invention relates to a tool for drivingfastenings, as for 'ex-.imple tacks, for securing welts with spreadable portions, and will be best understood from the following 5 description when read in the light ofthe accompanying drawing of one example of `the invention, while the scope of the inventlon will be more particularly pointed out 1n the appended claims.

In the drawing Fig. 1 is an elevation of the tool constructed according to my invention;

FFig. 2 is an elevation at right angles to ig. 1; A

Fig. 3 is a section on the line 3-3 of Fig.4is a fragmentary View corresponding to a section on the line 4 4 of Fig. 1,

illustrating the tool applied to a Welt for the purpose of setting a tack; and

Fig. 5 is a View corresponding to Fig. 4 with the parts in a different position.

Referring to the drawing a support is provided in the form of a tubular body 1 in the bore 3 Aof which is rcciprocably mounted a plunger 5 ing means. At its outer end the tool is provided' with an operating means in the form of a head 7 for the plunger, a coil spring 9 surrounding the plunger and abutting at opposite ends respectively with the head and the end 1l of the support being provided for automatically returning the plunger when the head is released after being pushed toward the support for driving the fastening. Adjacent its end opposite the head 7 the plunger' carries a. transversely positioned in 13 the opposite projecting ends of which slide in the oppositely disposed slots 15 in the Walls of the support.

As illustrated, opposite sides of the support areflattened as indicated at 17, these flattened portions being recessed as in dlcated at 19 for providing grooves receiving and guiding the flat spring members 21.

For securing the springs to the support the present construction .provides plates 23 which lit the grooves 19 and are placed over the springs, the plates being secured to the support .byqneans of screws 25.

vThe spring members at their forward endsare shown as converging toward each other as indicated at 27, herein providing a of a fastening driv apart a distance sufficient to permit the fas-A tening engaging part 29 to pass between them. Herein the ends of the springs are notched as is indicated at to permit the springs to be passed over the head of `a--tack or the like employed for securing the welt in position, this construction also providing means :for aligning the tack .driving means with the tack.

In Figs. 4 and 5 I have indicated a Welt having the base 37 and the portions 39 sewcd to the base by stitches indicated at 41, the position of the stitches and the resiliency'of the portions 29 permitting the latter to be spread apart to allow the tack or other fastening means to be driven. will be understood, normally the two portions 39substantially abut at their adjacent edges. Vhen the welt is to be applied the fastening means may be driven for a part of their length as indicated by the tack shown at 43 in Fig. 4. The tool isthen applied as indicated in Fig. 4, the notches 35 at the end of the springs serving to permit the springs to pass ,the head of the tack and to center the head of the tack with the tack engaging part 29. Forcing the plunger 3 into the positionshown by` Fig. 5 will cause the tack to be driven vand the springs to force tlie spreadable portions 39 apart sufiiciently to permit entry `of the tack driving part between them. After the tack is driven and the tool is removed thesprea-dable parts 39 will spring back until their adjacent edges abu Although I have described for purposes of illustration .one example of the invention l* 'the spiritof the invention.

' Claims: i

1. A tool for driving fastenings for securing welts with spreadable portions having, in combination, means for spreading means, and fastening and welt-engaging yzo means for centering a partially driven fastening beneath said driving means and spreading said portions of the Welt to permit said driving means to pass between them.
